At Random? Or is it going to the 'Safe Home' location some what in the center of the print bed?
You have the right to ask for the source code for the firmware that was loaded on your printer when it shipped. When you look at its Configuration.h file... You will know exactly what your printer has been told to do. And if you want to change something... You just zap a couple of options in the Configuration.h file and reload the firmware.
It is a RepRap printer. You get to configure it how ever you want it to behave.
